To all whom it mayoncern:

Be it known that I, CARL E. BAUER, a cit1- zen of .the United States, r'esidin at Hammond, in the county of Lake an State of Indiana, have invented a new and useful of which the fo owing is a specification. n Thisl invention relates to improvements 1n cultivators. My improved cultivator is simple in construction and design, thus lowering the cost of production. t is also so designed that it can be easily operated.`

A device embodying the features of my invention is shown in the accompanying drawings, in which Figure 1 is `anview in side elevation, Fig. 2 is a topV plan view, Fig. 3 is a view taken as indicated b the line ofFi .1,Fig.4is'aviewt enasindicated. y the line 4 of Fig. 3,and Figs. 5 and 6 are views of different kinds of cultivator tools that can be used with the de'- vice.

As shown inthe drawings, indicates a pair of longitudinally arranged paralle frame members made preferably of channel iron, as shown. Each-of these members isv provided with a slight offset, as shown. The frame members 10 are joined near their forward ends by a pair of -cross members 11, on which are mounted the motor 12, here shown as an internal combustionA engine ofthe air cooled type. Y f

Near their forward ends, the frame members 10 are also joined on their under side by a plate 13, carrying pivotally supported atpeach end on its under side, in the usual manner, steering knuckles 14, which in turn carry the main supporting wheels The frame members 10 carry at their rear ends `substantially vertically arranged members" .16 joined at their upper ends by the hori-- zontal member 16l and carrying at their lower ends the rear supportingI and driving wheels 17. It will be noted that the frame members 10, thus joined at their forward ends and their rear ends, form a rigid frame.

The upper ends of the members 16 are provided with bearing supports 18 in which are rotatably mounted the controlling handles 19. The forward ends of the controlling handles 19 are rotatably supported inv the bearing members 20, which lare carried by the framemembers 10. The foward ends of the controlling handles 19 are provided with depending arms 21, whichare joined to .the oonnectmg red 22, whlch joins the steer-111s `vided at each end with a Appunti meermalen. 1e,- iaas. semi no. 001,205. j

knuckles 14 in the usual manner. The rear ends of the handles 19 are bent downwardly, as indicated by 19, so that steering may be effected by twisting the handles 19, thus turning the steerin knuckles and wheels A15. It is to be noted a that steerin Amay be effected by merely raisin the whee 15 and wn-gmg the machine a ut on the wheels About midway between their ends, the frame members 10 carry a counter-shaft 23 (see Fig. 3). The counter-shaft 23 is proyoke 24, having a. downwardly depending s eeve mounted on a shaft 26 carrying on its lower end a cultivating tool 27. Each shaft 26 is provided at its upper end with a bevel ar 28 meshing with a bevel ear 29 on the s aft 23. The shaft 23 is provi ed near its center with a sprocket wheel 30 adapted to be driven by a chain 31, which in turn is driven by the motor 12; VIt will be noted that, by this construction, the cultivator tools 27 will be 1 rotated.

Each cultivator tool 27 comprises a circular plate 27 mounted on the end of the shaft 26. Detachably mounted on the plate 27 are the cutters 27", each adapted for easy removal by removing the cap screws 27,

' which are threaded into the plate 27. By

means of this construction, it will be noted that the cutting tools 27b may be easily and uickly removed and other tools of different orms, as suggested in Figs. 5 and 6, as desired, substituted.

The counter shaft 23 is provided at its ends with sprockets 32 and the rear wheels 17 are provided with sprockets 33. The sprockets 32 and 33 are joined by the chains 34. In this manner the rear wheels 17 are given rotation by the motor 12 in a direction tending to drive the cultivator forward. By this construction, the rear wheels 17 operate both as supporting wheels and driving wheels. It will be noted, however, that these wheels may be easily lifted from the groundby merely raising the handles 19, thus stopping the driving as desired without stopping the motor or cultivator tools. The location of the motor or prime mover 12 enables ready changing of the center of gravity as the machine tilts withA respect to the axle 14 by raising of the handles 19',- Bein relatively small in diameter'or size, w eels 17 j are of minimum weight s0 as to facilitate the lifting @fthe shaft 23. These sleeves 25 carry, at their lower ends pivotally mounted thereon at a pair of bars 35 jolned at their rear ends` by the cross bar 36. The members 16, about midway between their ends, are joined by a horizontal bar 37. The lower edges of the` members 35 are rovided with a series Aof notches 38. By t 's construction, it is possible to vary the angularity between the sleeves 25 and the members 10 by raising the members 35 and.' engaging different notches with the bar 37. It is possible, therefore, to move the cultivator tools in various positions, such as indicated by the broken lines in Fig. 1. By this means, the cultivator tools may be set so that they will engage the ground deeply or only slightly; or, if desired, they may be swung to the rear and disengaged entirely from the round. Also, if desired, they may be pushe to a position forward of the vertical. By thus slanting the sleeves 25 forwardly or backwardly and equipping the plates 27 with the proper sha tools, the rotation of the tools against the ground being cultivated may be made to serve to assist in propelling the cultivator. For example, tools shaped such as suggested in Figs, 5 and 6, or tools having a substantially cork-screw shape. may be employed; and such tools with the proper angularity given to the sleeves 25 will, when rotated, assist in propellin the cultivator.

While l have shown an described certain embodiments of my invention, it is to be understood that it is capable of many modifications. Changes, therefore, in the construction and arrangement may be made without departing from the spirit and scope of the invention as disclosed in the appended claims, in which it is my intention to claim all novelty inherent in my invention as broadly as possible in view of the prior art.

What I claim as new and desire to secure by Letters Patent, is:

A cultivator including a frame, a prime mover on said frame adjacent the forward end thereof, a relatively large nondriven ground wheel journaled on the frame and having its axis below said prime mover and adjacent said forward end of the frame, a cultivating means on said frame in the rear of said axis, a ground wheel driven from the prime mover, the latter ground wheel being relatively small with respect to the non-driven ground wheel and supported on said frame in the rear of said cultivating means, and means extending from the frame engageable adjacent the rear of the machine to tilt the latter.

2. A cultivator including a frame having wheelcarried by and adjacent the lower end of sald member, a cu tivating means on said frame operable in front of said wheel,

a prime mover on the frame adjacent the forward end thereof to operate said wheel and cultivating means, a non-driven ground 1 wheel relatively large with respect to the first mentioned ground wheel; in advance of the cultivating means, the axis of the non-driven ground wheel vbeing below the primel mover and adjacent said forward end of the frame, and a controlling handle extending from the frame to the rear of said member and sup-ported by said member adjacent the upper end of the latter.

3. A cultivator including a frame, a shaft journaled transversely thereof, cultivating means depending from and in driven relation to said shaft, an arm extending rearwardly from said cultivating means, said frame having spaced upstanding members in the rear of said cultivating means disposed partly above and partly below the frame, ground wheels carried by said members adjacent their lower ends, controlling handles extending from said frame and sup'- ported by said upstanding members adjacent the upper 'ends of the latter, a rod spanning said members, and said arm havirg means for adjustable attachment to said r 4. A cultivator including a frame provided with front wheels, cultivating devices disposed one substantially in line with and rearwardly of each front wheel, means on the frame to support and drive said devices, upstanding members at the rear of said frame, rear wheels carried by said members, controlling handles in divergent relation extending from the frame and supported by said members, means connecting said members, arms extending intermediate said members and attachable to thelatter means, and said arms having forward outwardly offset connections to said devices.

5. A cultivator including a frame having upstanding members, cultivating means carried by the frame, said cultivating means having arms extending rearwardly therefrom and disposed 'intermediate and attached to said members, controlling handles, the forward ends of said arms being located outwardly of the adjacent portions of the handles, and said handles being in substantially crossed relation to and above the respective arms and supported by the upstanding members adjacent the outer side surfaces of the latter.

6. A cultivator including a'frame havlng ,longitudinally disposed substantially parallel frame members, a motor supported thereby adjacent one end, front wheels between which the motor is located, steering knuckle connections between said frame members and wheels, upstanding members adjacent the rear ends of said longitudinal frame members, rear wheels carried by the upstanding frame members aty their lower ends, controlling handles supported by said upstanding members adjacent the outer sides of the latter, said controlling handles adjacent their forward ends having connections with the steering knuckle connections intermediate the longitudinal frame members,'sha.ft means journaled on said longitudinal frame members driven from the motor, a cultivating device behind each vfront 15 wheel driven from said shaft means, arms extending from said devices in substantially crossed relation to the longitudinal frame members, and means to secure said bars to and intermediate the upstanding frame 20 members.
